Large displays from Calog

December 2014 Operator Interfaces, Switches & Relays

Calog offers a wide range of remote large displays that includes digit sizes from 20 up to 125 mm. These are available in both Polycarp and metal housings for 3, 4, 5 and 6 digit displays.

Standard input to the remote large display is RS-232 (or optional RS-485), with inputs of mA, mV, V, A, frequency, RTD, thermocouple and load cell made possible via an internal add-on circuit. Other features include:

• Excellent visibility from the ultra-bright LED digits.

• IP65 steel housing.

• Display range push button programmable via integrated indicator/transmitter.

• Full range of output options available on indicator.

The displays offer a wide range of applications where high visibility and viewing from long distances is required, such as:

• Downtime, time and production control in large factories.

• Clock and shift timing applications for manufacturing areas.

• Batch or product counting in manufacturing.

• Speed timing and control in manufacturing or service delivery. For example, the time a customer’s car is in a wash bay or on a lift for a tyre fitment.

• Remote large display for load cell batch quantities or crane overload protection.

• Remote large displays for belt weigh rate or total indication.

• Weighbridge weight indication for both driver and operator.

• Remote temperature indication for furnace and oven applications where an operator cannot get close to the furnace due to the high temperature.

• Temperature indication for baking applications were the speed of a conveyer is controlled based on the temperature of the oven. For example, a tile or bread-baking oven utilising a conveyer to control the time the product is run through the oven.
